Problems solved by technology

[0020] A micro-irrigation material with capillary penetration function and a preparation method thereof, the material does not contain a release agent and a surfactant, and the proportion of inorganic fillers is relatively high, which overcomes the poor water seepage effect and large investment of materials in the prior art , high cost of raw materials, long process flow, low production efficiency, and high overall production cost. At the same time, the material has a capillary seepage network composed of hydrophilic inorganic filler particles evenly distributed in the non-hydrophilic thermoplastic matrix. This structure not only ensures the processing and use performance of the material, but also can automatically seep or stop the water seepage through the capillary network inside the material according to the water potential of the soil in contact with it.

Embodiment 1

[0108] The by-product salt mud (slurry) of the chlor-alkali industry is removed with a plate and frame filter press to remove excess water and dried, then ground and sieved to obtain a 10 micron (μ) salt mud powder filler, using a melt flow rate (MFR) of 4 Linear low-density polyethylene (LLDPE) resin is used as the base material, and the mass fraction ratio of filler to resin is 300:100; auxiliary agent is: hindered phenol antioxidant is tetrakis[β-(3.5-di-tert-butyl, 4- Hydroxyphenyl) propionic acid] pentaerythritol ester, the addition is 0.3 parts by mass, and the phosphite stabilizer is three (2.4-di-tert-butylphenyl) phosphite, and the addition is 0.3 parts by mass; the average molecular weight is 4000 high flow polyethylene (PE wax), the addition amount is 1 part by mass; 40% carbon black master batch containing 35 parts by mass of carbon black. The above components are added in three stages according to the metering. The first stage adds all the resins, additives and fi...

Embodiment 2

[0110] Calcium carbonate of 6.5 microns (μm) is used as a filler, and a low-density polyethylene (LDPE) resin with a melt flow rate (MFR) of 0.3 is a base material, and the mass and number ratio of the filler to the resin is 200: 100; the auxiliary agent is : The hindered phenolic antioxidant is tetrakis [beta-(3.5-di-tert-butyl, 4-hydroxyphenyl) propionate] pentaerythritol ester, the addition is 0.3 parts by mass, and the phosphite stabilizer is tri(2.4 -Di-tert-butylphenyl) ester, the addition amount is 0.3 parts by mass; the melt flow rate (MFR) is 30 high flow polyethylene (PE), the addition amount is 1 parts by mass. Add the above components into the twin-screw granulator in three stages according to the metering. The first stage adds all the resins, additives and fillers in corresponding proportions. The proportion of fillers added in each stage is 40% and 40% of the total amount of fillers. , 20%, using a twin-screw granulator with a screw diameter of 75 (φ75) and a len...

Embodiment 3

[0112] Use 1.6 microns (μm) of calcium carbonate as a filler, a high-density polyethylene (HDPE) resin with a melt flow rate (MFR) of 0.1 as a base material, and the mass and number ratio of filler to resin is 150: 100; the auxiliary agent is: The hindered phenolic antioxidant is tetrakis [β-(3.5-di-tert-butyl, 4-hydroxyphenyl) propionic acid] pentaerythritol ester, the addition amount is 0.3 parts by mass, and the phosphite stabilizer is tri(2.4- Di-tert-butylphenyl) ester, the addition amount is 0.3 parts by mass; the high flow polyethylene (PE) whose melt flow rate (MFR) is 70, the addition amount is 3 parts by mass. Add the above components into the twin-screw granulator in four stages according to the metering. The first stage adds all the resins, additives and fillers in corresponding proportions. The proportion of fillers added in each stage is 30% and 30% of the total amount of fillers. , 30%, and 10%, use a twin-screw granulator with a screw diameter of 75 (φ75) and a...

Abstract

The invention relates to a seeping micro-irrigation container and a preparation method thereof. The container is made of a micro-irrigation material with a capillary water seeping function, has a three-dimensional network capillary water seeping structure of inorganic particles and thermoplastic plastics, and has a power-free self-adaptation, continuous and balanced seeping function. According to water potential of soil contacted with the container, water can seep outwards automatically through the capillary network structure inside the container or stop seeping outwards. The container further comprises a gel protective layer (11). The container has good water seeping capacity, can prevent blocking, bacteria and rats, can be used as a mini reservoir independently, can also be connected with a pipeline system, and forms a power-free self-adaptation, continuous and balanced seeping micro-irrigation system.

Description

technical field [0001] The invention relates to a water-saving micro-irrigation container, in particular to a buried irrigation container with water seepage function. Background technique [0002] my country's water resources only account for 6% of the world's total, which is more scarce than cultivated land resources (accounting for 9% of the world's total). The shortage of water resources has become a bottleneck that seriously restricts the sustainable development of my country's national economy. Agriculture is the industry that consumes the most water in my country, accounting for more than 70% of the total water consumption, of which the water consumption for farmland irrigation accounts for 90% to 95% of the agricultural water consumption. However, the coexistence of shortage of water resources and waste of water resources in our country is very serious. Due to backward irrigation technology, serious waste of water resources and low utilization efficiency have exacerb...
